I find selecting the action for the cards very hard on mobile. Is there any advice for this? It's difficult to choose whether ti play, discard or build your wonder with a card when pressing the screen on a mobile device.

Not [currently] on a mobile device here, but last game i played i was completely unable to select which option [build the structure of the selected card, burn the card to fulfill a wonder, or sell the card for 3] to use when selecting a card.

Is there supposed to be a pop-up option list once you've selected a card??
